Description

Die Erfindung betrifft einen Klebestreifen für rückstandsfrei und zerstörungsfrei wiederlösbare Verklebungen durch Ziehen/Verstrecken in der Verklebungsebene sowie mit diesem Klebestreifen verklebte oder verklebbare Haken und Basisplatten.The invention relates to an adhesive strip for residue-free and non-destructive releasable bonds by pulling / stretching in the bond plane as well hooks and base plates glued or glued with this adhesive strip.

Hochdehnbare elastisch oder plastisch unter Verstreckung deformierende, einseitig oder beidseitig haftklebrige Selbstklebebänder (Klebstoff-Folien), die durch Ziehen im wesentlichen in Richtung ihrer Verklebungsebene rückstands- und zerstörungsfrei wiederablösbar sind, sind bekannt. Mit ihnen hergestellte Verklebungen bieten kraftvollen Halt und lassen sich doch spurlos wiederablösen, sei es mit nur geringer Beschädigung des Untergrundes oder der Fügeteile oder gar ohne.
Beispielhafte Klebebänder vorgenannter Art sind in US 4,024,312, DE 33 31 016, DE 42 22 849, WO 92/11332, WO 92/11333, US 5,516,581 und WO 95/06691 beschrieben.
Highly stretchable self-adhesive tapes (adhesive films) which are elastically or plastically deformable under stretching and which are pressure-sensitive on one or both sides and which can be removed without residue and non-destructively by pulling essentially in the direction of their bond plane are known. Bondings made with them offer a powerful hold and can be removed again without a trace, be it with little damage to the surface or the parts to be joined or without.
Exemplary adhesive tapes of the aforementioned type are described in US 4,024,312, DE 33 31 016, DE 42 22 849, WO 92/11332, WO 92/11333, US 5,516,581 and WO 95/06691.

Eine häufige Konfektionierform entsprechender Produkte sind Selbstklebebandzuschnitte, zum Beispiel in Form rechteckiger Streifen, welche an einem Ende einen klebfreien Anfasserbereich besitzen (siehe DE 42 22 849, WO 92/11333 beziehungsweise US 5,516,581). Der Anfasser dient als Grifffläche für ein späteres Wiederablösen des Klebebandes. Im Handel sind solche Produkte unter der Bezeichnung "tesa Power-Strips" ® erhältlich.A common form of assembly of corresponding products are self-adhesive tape cuts, for example in the form of rectangular strips with a non-tacky end Have a handle area (see DE 42 22 849, WO 92/11333 and US No. 5,516,581). The handle serves as a grip surface for later removal of the Tape. Such products are commercially available under the name "tesa Power-Strips" ® available.

Praktische Probleme mit o. g. Produkten treten dann auf, wenn im Falle von doppelseitig haftklebrigen Selbstklebebändern das Selbstklebeband beim Ablöseprozeß reißt. Dieser Problematik nehmen sich insbesondere DE 42 22 849, DE 44 28 587 und DE 44 31 914 an. In der DE 42 22 849 beschriebene Klebebänder nutzen UV-undurchlässsige Anfasserabdeckungen, welche die Reißerneigung im Anfasserbereich nach UV-Exposition reduzieren beziehungsweise verhindern sollen. In der DE 44 28 578 beschriebene Klebebänder verfügen über ein besonders ausgeformtes Ende, welches einem partiellen Reißen des Klebebandes zum Ende des Ablöseprozesses entgegenwirkt. DE 44 31 914 beschreibt Klebebänder, welche im Anfasserbereich u. a. spezielle Folien- oder Papierabdeckungen aufweisen, die eine geringe Adhäsion zur verwendeten Selbstklebemasse besitzen, wodurch die Reißerneigung im Bereich des klebfreien Anfassers reduziert wird. Eine allgemeine Lösung der Reißerproblematik steht dennoch aus.Practical problems with the above Products occur when in the case of double-sided adhesive self-adhesive tapes the self-adhesive tape tears during the detachment process. This DE 42 22 849, DE 44 28 587 and DE 44 31 914 are particularly problematic on. Adhesive tapes described in DE 42 22 849 use UV-impermeable tapes Handle covers that show the tendency to tear in the handle area after UV exposure reduce or prevent. Described in DE 44 28 578 Adhesive tapes have a specially shaped end, which is a partial Tear the tape counteracts at the end of the peeling process. DE 44 31 914 describes adhesive tapes which u. a. special foil or Have paper covers that have low adhesion to the used Have self-adhesive, causing the tendency to tear in the area of non-adhesive Handle is reduced. There is still a general solution to the problem of tearing out.

Mit der DE 37 14 453 C1 wird eine Möglichkeit offenbart, einen Übungssprengkörper an einem Untergrund zu befestigen, indem dieser mittels eines doppelseitigen Klebebands verklebt wird, wobei zwischen Klebeband und Übungssprengkörper ein Stripband angeordnet ist. Zur Lösung der Verklebung wird an einem an dem Stripband vorhandenen Anfasser gezogen. Eine Beschichtung des Anfasser ist nicht vorhanden, der Anfasser steht frei heraus.DE 37 14 453 C1 discloses a possibility of attaching a training explosive device to attach to a surface by means of a double-sided adhesive tape is glued, with a strip tape between the tape and the explosive device is arranged. To solve the bond, an existing one on the strip tape Handle pulled. There is no coating on the handle, the handle stands out freely.

Ein bevorzugtes Anwendungsgebiet von durch Verstrecken im wesentlichen in der Verklebungsebene rückstands- und zerstörungsfrei wiederablösbaren Selbstklebebändem ist die Verklebung von Haken oder vergleichbaren Vorrichtungen, wie sie u. a. aus der DE 42 33 872 bekannt sind. In dieser wird ein Haken beschrieben, der mittels eines Streifens einer Klebfolie auf dem Untergrund verklebt wird, wobei der Klebfolienstreifen einen nichtklebenden Anfasser aufweist. Um den Haken wieder vom Untergrund zu lösen, wird der Klebfolienstreifen in der Verklebungsebene am Anfasser durch Zug gestreckt, worauf es zur Entklebung kommt. Damit der Haken wieder vom Untergrund gelöst werden kann, ist es zwingend notwendig, daß der Klebfolienstreifen so unter dem Haken verklebt wird, daß der Anfasser sichtbar und vor allem greifbar ist.
Dieser stets sichtbare Anfasser trübt naturgemäß den optischen Eindruck des verklebten Hakens, beinhaltet aber auch technische Nachteile, denn der Anfasser ist äußeren Belastungen schutzlos ausgeliefert. Erhöhte UV-Strahlung oder auch Lösungsmittel führen zu einer Beeinträchtigung der Stabilität des Anfassers, mitunter kann dieser dann beim Ablösen unter der Zugeinwirkung ab reißen. Eine Trennung des Hakens vom Untergrund ist dann nur noch unter Zerstörung des Untergrunds oder des Hakens möglich.
Solche Haken sind bereits im Handel erhältlich, und zwar unter dem Namen "tesa Power-Strips mit Haken"®.
A preferred field of application of self-adhesive tapes which can be removed without leaving residues and without destruction by stretching essentially in the bonding plane is the bonding of hooks or comparable devices, as are known, inter alia, from DE 42 33 872. This describes a hook that is glued to the substrate by means of a strip of adhesive film, the adhesive film strip having a non-adhesive handle. In order to detach the hook from the surface again, the adhesive film strip is stretched in the adhesive layer on the handle by pull, which leads to detackification. So that the hook can be detached from the surface again, it is imperative that the adhesive film strip is glued under the hook so that the handle is visible and above all tangible.
This handle, which is always visible, naturally obscures the visual impression of the glued hook, but also contains technical disadvantages, since the handle is delivered without any protection against external loads. Increased UV radiation or solvents lead to an impairment of the stability of the handle, which can sometimes tear off when removed under the action of the pull. A separation of the hook from the base is then only possible by destroying the base or the hook.
Such hooks are already commercially available, namely under the name "tesa Power-Strips with hooks" ®.

Einen vergleichbaren Haken offenbart die PCT-Anmeldung WO 94/21157. Der in dieser gezeigte Haken verwendet eine Klebfolie, die hochelastisch und des weiteren nicht rückstellend ist.PCT application WO 94/21157 discloses a comparable hook. The one in this The hook shown uses an adhesive film that is highly elastic and furthermore not is resettable.

Weiterhin sind im Handel die sogenannten "tesa Power-Strips Systemhaken" ® erhältlich. Zum Anbringen dieser auf dem Untergrund wird zunächst eine Basisplatte mittels eines Streifens der erwähnten Klebfolie verklebt, wobei wieder der Anfasser sichtbar bleiben muß. Auf die Basisplatte wird dann der jeweilige Haken aufgesteckt.The so-called "tesa Power-Strips system hooks" ® are also commercially available. To attach this to the surface, a base plate is first of all by means of a Strips of the above-mentioned adhesive film are glued, the handle remaining visible again got to. The respective hook is then placed on the base plate.

Die in den vorgenannten Druckschriften dargestellten Klebsysteme und Haken weisen eine Anzahl von Nachteilen auf.The adhesive systems and hooks shown in the aforementioned publications have a number of disadvantages.

Problematisch ist bei Haken und dergleichen des Standes der Technik, wie bereits oben erwähnt, die optische Abdeckung des Anfassers, der zum späteren Ziehen die Vorrichtung überragen muß, und zwar zum Schutz dieses Anfassers vor Manipulation oder Beschädigung, insbesondere Schaden durch UV-Licht.
Um die erwünschte und teilweise erforderliche Abdeckung des Anfassers zu gewährleisten zu können, müssen die mit dem Klebfolienstreifen zu verklebenden Gegenstände eine Tragfläche aufweisen, die den gesamten Klebfolienstreifen, also inklusive des überstehenden Anfassers abdeckt.
The problem with hooks and the like of the prior art, as already mentioned above, is the optical covering of the handle, which must protrude beyond the device for later pulling, to protect this handle from manipulation or damage, in particular damage by UV light.
In order to be able to ensure the desired and sometimes necessary covering of the handle, the objects to be bonded with the adhesive film strip must have a wing which covers the entire adhesive film strip, that is to say including the protruding handle.

Noch deutlicher tritt das Problem bei den Systemen mit den Basisplatten auf. Mittels des Klebestreifens wird die Basisplatte auf dem Untergrund fixiert, und zwar derart, daß die Basisplatte den klebenden Bereich des Klebestreifens abdeckt und gleichzeitig der nichtklebende Anfasser frei hervorsteht. Auf die Basisplatte wird -vergleichbar einem Adaptersystem- ein Körper aufgesteckt, der einen Haken, Deckenhaken oder eine sonstige Befestigungsvorrichtung trägt. Dieser Körper muß nun wieder die Basisplatte mitsamt des freien Anfassers bedecken, um neben der Erfüllung der genannten technischen Anforderungen einen optisch einwandfreien Eindruck zu erzielen.
Der Körper bedeckt eine relativ große Fläche des Untergrunds, muß also selbst eine gewisse Größe aufweisen. Diese bauliche Größe wird oft als unschön empfunden. Des weiteren ist sie technisch eigentlich nicht erforderlich, weil die Fläche, die die Verklebung der Basisplatte sichert, viel kleiner ist. Eigentlich muß lediglich die Basisplatte abgedeckt werden, wenn der Anfasser nicht vonnöten wäre.
Hier will die Erfindung ansetzen.
The problem occurs even more clearly with the systems with the base plates. The base plate is fixed on the substrate by means of the adhesive strip, in such a way that the base plate covers the adhesive area of the adhesive strip and at the same time the non-adhesive handle protrudes freely. Comparable to an adapter system, a body is placed on the base plate, which carries a hook, ceiling hook or other fastening device. This body must now cover the base plate together with the free handle in order to achieve a visually perfect impression in addition to the fulfillment of the technical requirements mentioned.
The body covers a relatively large area of the subsoil, so it must itself have a certain size. This structural size is often perceived as unattractive. Furthermore, it is not actually technically necessary because the area that secures the base plate is much smaller. Actually, only the base plate has to be covered if the handle was not needed.
This is where the invention wants to start.

Aufgabe der vorliegenden Erfindung ist es, die vorgenannten Nachteile zu überwinden, also eine Möglichkeit zu bieten, die bisher erforderlichen großen Abdeckungen für die mittels der Klebestreifen verklebten Haken beziehungsweise für die mittels der Klebestreifen verklebten Basisplatten zu verringern.The object of the present invention is to overcome the aforementioned disadvantages, So a way to offer the previously required large covers for the hooks glued by means of the adhesive strips or for those by means of Adhesive strips to reduce glued base plates.

Gelöst wird diese Aufgabe durch Klebestreifen, wie sie näher in den Ansprüchen gekennzeichnet sind. Gegenstand der Unteransprüche sind vorteilhafte Ausführungsformen der Klebestreifen sowie Haken und Basisplatten, die mit diesen verklebbar sind sowie mit diesen verklebt worden sind.This task is solved by adhesive strips, as described in the claims Marked are. Subject of the subclaims are advantageous Embodiments of the adhesive strips, as well as hooks and base plates, with these are glued and have been glued to them.

Demgemäß betrifft die Erfindung einen Klebestreifen mit klebendem Bereich und Anfasser für eine rückstandsfrei und zerstörungsfrei wiederlösbare Verklebung, wobei der Klebestreifen ein solcher ist, der durch ZiehenNerstrecken in der Verklebungsebene lösbar ist, wobei der Anfasser, an dem durch Ziehen/Verstrecken in der Verklebungsebene die Verklebung wieder lösbar ist, in Richtung des klebenden Bereiches des Klebestreifens umgelegt ist oder vorzugsweise umgelegt und reversibel fixiert ist.Accordingly, the invention relates to an adhesive strip with an adhesive area and handle for a residue-free and non-destructively releasable bond, the Adhesive tape is one that is pulled by stretching in the bond plane is releasable, the handle on which by pulling / stretching in the bonding plane the bond can be released again, in the direction of the adhesive area of the adhesive strip is folded or preferably folded and reversibly fixed.

Bevorzugt besteht der Klebestreifen aus einem hochverstreckbaren, elastisch oder plastisch unter Dehnung verformbaren Material, gegebenenfalls mit einem Zwischenträger, insbesondere mit einem Folien- oder Schaumstoff-Zwischenträger.
Die Adhäsion der Klebfolie sollte geringer sein als die Kohäsion, das Haftvermögen beim Dehnen der Folie weitgehend verschwinden und das Verhältnis von Abzugskraft zu Reißlast mindestens 1 : 1,5 sein.
Vorzugsweise ist der Klebestreifen ein solcher auf Basis von thermoplastischem Kautschuk und klebrigmachenden Harzen mit hoher Elastizität und geringer Plastizität.
Die Klebestreifen können einseitig oder beidseitig haftklebrig oder auch einseitig oder beidseitig mit einer thermisch aktivierbaren Klebmasse ausgerüstet sein. Ihr Aufbau kann einschichtig oder mehrschichtig ausgeführt sein. Im Falle beidseitig haftklebriger Selbstklebebänder können als Zwischenträger elastisch oder plastisch deformierende Materialien genutzt werden. Hierin eingeschlossen sind neben Kunststoffolien insbesondere Klebmassen als Zwischenschichten und schaumstoffhaltige Zwischenträger. In einer bevorzugten Ausführungsform weist die Klebfolie einen Zwischenträger auf, der beidseitig mit einer Acrylatkleberbeschichtung versehen ist. Erfindungsgemäße Klebestreifen werden demgemäß durch selektive Beschichtung geeigneter nicht haftklebriger Trägermaterialien erhalten.
In diesem Fall werden die Anfasserbereiche durch den genutzten Träger gestellt, welcher derart partiell mit Klebmasse beschichtet oder bedruckt wird, daß die Anfasserbereiche nicht mit Klebstoff bedeckt sind.
The adhesive strip preferably consists of a highly stretchable, elastically or plastically deformable material under stretch, optionally with an intermediate carrier, in particular with a film or foam intermediate carrier.
The adhesion of the adhesive film should be less than the cohesion, the adhesive strength should largely disappear when the film is stretched, and the ratio of peel force to tear load should be at least 1: 1.5.
The adhesive strip is preferably one based on thermoplastic rubber and tackifying resins with high elasticity and low plasticity.
The adhesive strips can be provided on one or both sides with pressure-sensitive adhesive or on one or both sides with a thermally activatable adhesive. They can be constructed in one or more layers. In the case of pressure-sensitive self-adhesive tapes on both sides, elastically or plastically deforming materials can be used as intermediate carriers. In addition to plastic films, this includes in particular adhesives as intermediate layers and foam-containing intermediate carriers. In a preferred embodiment, the adhesive film has an intermediate carrier which is provided on both sides with an acrylate adhesive coating. Adhesive strips according to the invention are accordingly obtained by selective coating of suitable non-pressure-sensitive carrier materials.
In this case, the grip areas are provided by the carrier used, which is partially coated or printed with adhesive so that the grip areas are not covered with adhesive.

Erfindungsgemäße Klebestreifen werden in konfektionierter Form, etwa in Form von Stanzlingen oder Zuschnitten eingesetzt. Konfektionierte Ware weist einen zentralen haftklebrigen Bereich auf. An diesen angrenzend finden sich mehrere, jedoch wenigstens ein Anfasserbereich.Adhesive strips according to the invention are in ready-made form, for example in the form of Die cuts or blanks used. Assembled goods have a central sticky area. Adjacent to these are several, but at least a handle area.

Konfektionierformen umfassen neben Klebebandstücken definierter Abmessungen, zum Beispiel in Form von Stanzlingen oder Zuschnitten, wie zuvor beschrieben, gleichfalls Klebebandrollen, bei denen erst der Nutzer den endgültigen Zuschnitt des zu verwendenden Selbstklebebandes durch zum Beispiel Zuschneiden vornimmt. Beispiel für eine entsprechende Klebebandrolle ist die eines mit zum Beispiel einem Trennpapier abgedeckten doppelseitig haftklebrigen Klebebandes, dessen Klebmassenoberfläche in beiden Kantenbereichen beidseitig durch zum Beispiel Auflegen einer dünnen Polyesterfolie inertisiert wurde.Packaging forms include pieces of adhesive tape of defined dimensions, for Example in the form of die cuts or blanks, as previously described Adhesive tape rolls, in which only the user cut the final cut to be used Self-adhesive tape by cutting for example. example for a corresponding roll of adhesive tape is one with, for example, a release paper covered double-sided pressure-sensitive adhesive tape, the surface of the adhesive in both edge areas on both sides by, for example, applying a thin polyester film was rendered inert.

Erfindungsgemäße Klebebänder lassen sich ausgehend von ein- oder beidseitig haftklebrigen Selbstklebebänder, welche durch Verstrecken im wesentlichen in Richtung der Verklebungsebene rückstands- und zerstörungsfrei wiederablösbar sind, durch partielle Inertisierung der Haftkleberoberfläche selbiger Klebebänder erhalten.Adhesive tapes according to the invention can be started from one or both sides pressure-sensitive self-adhesive tapes, which are stretched essentially in the direction the adhesive level can be removed without leaving any residue or damage, by partial inertization of the surface of the same adhesive tapes.

Die Inertisierung der Klebmasseoberfläche zur Bildung des Anfassers kann durch Abdeckung durch zum Beispiel dünne Folien aus zum Beispiel Kunststoff oder durch Abdeckung mit dünnen Papieren vorgenommen werden. Alternativ kann eine Beschichtung oder Bedruckung der zu inertisierenden Haftklebmassebereiche mittels eines nicht klebrigen Lacks oder eines nichtklebrigen pulverförmigen Materials durchgeführt werden. Bevorzugterweise wird die Inertisierung entsprechend DE 44 31 914 realisiert.
Die Inertisierung kann dabei so durchgeführt werden, daß der Klebestreifen im Bereich des gewünschten Anfassers im Vergleich zur Klebkraft des Klebestreifens nur eine geringe Klebkraft aufweist. Dies ist möglich durch eine gezielt partielle Bedruckung oder Beschichtung.
The surface of the adhesive composition can be rendered inert to form the handle by covering it with, for example, thin films made of, for example, plastic, or by covering it with thin papers. Alternatively, a coating or printing of the areas of PSA to be rendered inert can be carried out using a non-tacky lacquer or a non-tacky powdery material. Inertization according to DE 44 31 914 is preferably implemented.
The inerting can be carried out in such a way that the adhesive strip in the area of the desired handle has only a low adhesive strength compared to the adhesive strength of the adhesive strip. This is possible through targeted partial printing or coating.

Bevorzugt wird die Inertisierung der Klebmassenoberfläche bzw. die Beschichtung eines geeigneten Trägers mit Haftklebemasse bei beidseitig haftklebrigen Klebstoff-Folien näherungsweise deckungsgleich auf beiden Seiten durchgeführt.The inertization of the adhesive surface or the coating of one is preferred suitable carrier with pressure-sensitive adhesive in the case of pressure-sensitive adhesive films on both sides performed approximately congruently on both sides.

Insbesondere bei Klebfolien mit Zwischenträger, der beidseitig mit einer Klebebeschichtung versehen ist, kann das erfindungsgemäß vorgeschlagene Umlegen des Anfassers erfolgen, indem der Anfasser umgeknickt wird, gegebenenfalls unter Zuhilfenahme von Werkzeug wie beispielsweise einer Zange, so daß sich eine bleibende Verformung einstellt. Eine weitergehende Fixierung ist hier nicht notwendig.Especially in the case of adhesive films with an intermediate carrier, which is coated on both sides with a Adhesive coating is provided, the folding proposed according to the invention of the handle can be done by bending the handle, if necessary under Using tools such as pliers, so that there is a permanent Deformation sets. A further fixation is not necessary here.

Die unbeschichteten Anfasserbereiche werden in einer weiteren bevorzugten Ausführungsform erfindungsgemäß zumindest einseitig vollflächig oder partiell mit einer haftklebenden Beschichtung ausgerüstet, also einer Beschichtung, die im Vergleich zum eigentlichen Kleber eine geringere Haftkraft aufweist, beziehungsweise mit dem Kleber, wie er zur Beschichtung des Zwischenträgers genutzt wird.
Der Auftrag kann in Form von einem oder mehreren Punkten oder sonstig geformten Varianten erfolgen, die gegebenenfalls mit einem Schutzpapier abgedeckt sind.
In a further preferred embodiment, the uncoated handle areas are, according to the invention, provided with a pressure-sensitive adhesive coating on at least one side over the entire surface or partially, i.e. a coating which has a lower adhesive force than the actual adhesive, or with the adhesive as used for coating the intermediate carrier.
The application can take the form of one or more dots or other shapes, which may be covered with a protective paper.

Insbesondere wenn der Klebestreifen ein solcher auf Basis von thermoplastischem Kautschuk und klebrigmachenden Harzen ist mit hoher Elastizität und geringer Plastizität und demgemäß keinen Zwischenträger aufweist, wird der Anfasser dadurch gebildet, daß der Klebestreifen an einem Ende oder an beiden Enden beiderseits mit Abdeckungen versehen ist, die als Anfasser dienen.
Als besonders vorteilhaft hat sich herausgestellt, wenn zumindest eine der genannten Abdeckungen wenigstens einen Durchbruch aufweist. Beim Umlegen des Anfassers, zum Beispiel nachdem eine Basisplatte mit diesem verklebt worden ist, verklebt der freiliegende Klebstreifenkleber mit der Basisplatte. Aufgrund der relativ geringen Fläche ist die Klebkraft allerdings so gering, daß der Anfasser problemlos wieder aufgenommen werden kann.
In particular, if the adhesive strip is based on thermoplastic rubber and tackifying resins with high elasticity and low plasticity and accordingly has no intermediate carrier, the handle is formed in that the adhesive strip is provided at one end or at both ends with covers which serve as a handle.
It has proven to be particularly advantageous if at least one of the covers mentioned has at least one opening. When the handle is flipped over, for example after a base plate has been glued to it, the exposed adhesive tape glues to the base plate. Due to the relatively small area, the adhesive force is so low that the handle can be easily resumed.

Weiter vorzugsweise Falle ist zumindest eine der Abdeckungen mit dem Haftkleber ausgerüstet, sei es vollflächig, sei es partiell.
In einer weiteren bevorzugten Ausführungsform sind der oder die klebend ausgerüsteten Seiten des Anfassers mit einer abhäsiv ausgerüsteten Abdeckung versehen.
Auch hier hat es sich vorteilhaft herausgestellt, wenn zumindest eine der genannten Abdeckungen wenigstens einen Durchbruch aufweist. Denn so kann der Anfasser einfach umgelegt werden, ohne daß die Abdeckung zuvor entfernt werden muß.
It is furthermore preferable for at least one of the covers to be equipped with the pressure-sensitive adhesive, be it over the full area or partially.
In a further preferred embodiment, the side or sides of the handle which are equipped with adhesive are provided with a cover which is equipped with an adhesive.
Here, too, it has been found to be advantageous if at least one of the covers mentioned has at least one opening. This way, the handle can easily be flipped over without the cover having to be removed beforehand.

Die erwähnten Durchbrüche geben den Zugang zu einer offenen Fläche Klebmasse frei, die eine gewisse Klebkraft erzeugt. Gegebenenfalls ist diese ebenfalls mit einer Abdeckung ausgerüstet. Allerdings können die Anfasser auch auf die Abdeckung der eigentlichen Klebestreifen zurückgefaltet werden, so daß man zum einen eine Abdeckung einspart, zum anderen auch gleich die zum Abverkauf des Klebestreifens erforderliche Umverpackung verringert.The breakthroughs mentioned give access to an open area of adhesive, which creates a certain adhesive force. If necessary, this is also with a Cover equipped. However, the handles can also cover the actual adhesive strips are folded back so that you have a cover saves, on the other hand, the necessary to sell the adhesive tape Outer packaging reduced.

In einer weiteren bevorzugten Ausführungsform sind an dem Klebestreifen mehrere Anfasser vorhanden, die je nach Anforderung alle oder nur einzeln haftklebend ausgerüstet sein können.In a further preferred embodiment, there are several on the adhesive strip Handle available, all or only individually adhesive depending on the requirement can be equipped.

Schließlich umfaßt die Erfindung einen Haken sowie eine Basisplatte, die mit dem erfindungsgemäßen Klebestreifen, wie er in der obigen Beschreibung dargelegt worden ist, auf einem Untergrund verklebbar sind beziehungsweise verklebt sind.
Gerade die Basisplatte bietet eine hervorragende Möglichkeit, den Erfindungsgedanken weiter fortzuführen. Vom Schutzgedanken umfaßt ist eine Basisplatte, auf der der Klebestreifen bereits aufgeklebt ist, so daß auf eine Abdeckung des Klebestreifens verzichtet werden kann. Der erfindungsgemäß klebend ausgerüstete Anfasser kann umgelegt werden und auf der Basisplatte fixiert werden. Basisplatte und derartig befestigter Klebestreifen bilden eine Einheit, der sehr verpackungssparend und kundenfreundlich plaziert werden kann. Weiterhin ist diese Einheit problemlos auf einem Untergrund verklebbar, indem die zweite Seite des Klebestreifens von der Abdeckung befreit wird und die Einheit an der gewünschten Stelle verklebt wird.
Auch entsprechend mit einem Klebestreifen ausgerüstete Haken weisen die gleichen Vorteile auf.
Ein weiterer Vorteil des umgelegten Anfassers auf der Basisplatte besteht darin, daß, wenn auf die Basisplatte ein Haken aufgesetzt wird, ein Klemmeffekt des Hakens auf der Basisplatte zustande kommt, was das gelegentlich auftretende Klappern des Hakens auf der Basisplatte verhindert oder zumindest verringert.
Finally, the invention comprises a hook and a base plate which can be glued or glued to a surface using the adhesive strip according to the invention, as set out in the above description.
The base plate offers an excellent opportunity to continue the idea of the invention. The protective concept encompasses a base plate on which the adhesive strip is already glued, so that there is no need to cover the adhesive strip. The handle equipped with adhesive according to the invention can be folded over and fixed on the base plate. The base plate and the adhesive strips fastened in this way form a unit which can be placed in a packaging-saving and customer-friendly manner. Furthermore, this unit can easily be glued to a surface by removing the cover from the second side of the adhesive strip and gluing the unit at the desired location.
Hooks equipped with an adhesive strip also have the same advantages.
Another advantage of the flipped handle on the base plate is that when a hook is placed on the base plate, a clamping effect of the hook on the base plate occurs, which prevents or at least reduces the occasional rattling of the hook on the base plate.
